It is not just financial resources - it is also a factor of time to 
build a filter / set of filters from scratch (even with spamassasin + 
bogofilter you need to train it extensively, and tweak its rulesets to 
suit your mail flow).

there are some online spam archives that you can download and feed, and
while it may take you a little time to write a script to push the archives
at your spam filter (and if you push the archive at the filter multiple
times, it may learn faster), you will have written a portable tool that
you can use again and again, and will have tailored your email filters 
the way you want, rather than the way someone else wanted.  teaching your
users to foward spam to spam () yourdomain com will also speed that process
 
Sometimes outsourcing corporate / isp mail handling to a provider like 
us, criticalpath, postini etc might be a good way to go.

i am no longer associated with them, but usa.net has some good stuff too,
and while i would, for financial reasons, prefer to roll my own, 
outsourcing can be an effective way to manage your email, but it comes
down to a cost/benefit analysis.

Or you might elect to get a managed antispam solution that plugs into 
your mta (kind of like brightmail or spamsquelcher.org)

brightmail is quite good
 
The unix way - one tool per job.  Build a mail system out of components 
- it is often the best way to go.

i agree - like i said above, you can tailor it to suit your needs.  one
size does not necessarily fit all
